Different from traditional development methodologies like waterfall model, the CBD (component based development) methodology relies on a building block approach in the design and development of information system. The audit procedure and checklist for the traditional IS development methodology are required to be modified to be suitable for CBD. This research reviewed IS audit guidelines for the existing development process and analyzed multiple projects that employed the by component based development process. For the purpose of this study, we chose a governmental project and a next-generation IS project of a financial agency as sample cases. By comparing existing IS audit checklists and items actually reviewed in audit projects, this study identified appropriate check items for the CBD-centric audit program. New items were proposed as additional items such as project control in management phase, usage case and conceptual model establishment, component evaluation and design, in implementation phase, and so forth. The result of the research provides new guidelines for the audit CBD projects for the purposed of increased efficiency and qualify of application development projects.

Agile is a software development methodology which was established for four objectives; people, collaboration, responsiveness, and working software. Thus the Agile methodologies have been applied not only software development fields but also various special areas of technology. ESA (European Space Agency) adopt several Agile methodologies, including Scrum as the key technique, for the software development of ground segment. This article analyzes trends of Agile methodologies and introduction cases of the methodologies for ESA's ground segment software development.

The rapid development of information technology has much influence on architectural design. Collaboration beyond time and space has been possible by networking the work environment and digital products. Thus, the virtual design studio on architectural design is getting more important than ever before. This research investigates a virtual design studio methodology for effective collaboration. The building design process and the communication model are studied and possible modes of design collaboration are defined. This paper proposes an internet-based Virtual Reality(VR) communication tool as well as new design methodology that we call the 'Hybrid Design Methodology'. We expect that this design methodology will dramatically increase design feedbacks, and thus results in better design alternatives. There are two issues involved in developing the collaborative virtual design studio: 1) an intuitive interface that presents collaborative relations, and 2) three-dimensional computer-mediated communication tool using sketch as a modeling method. Further research issues identified at the end of the research include developing algorithms that translate mapping images to polygons for the drafting phase in the design process.

The spotlight is thrown on the ubiquitous technology these days, and diverse management technologies are proposed to efficiently manage the networks in the ubiquitous environment. Because each network has its unique management technology, the integrated management of complex networks is a very difficult challenge. In this paper, an integrated network management methodology is proposed to ensure the efficient management of different networks using ontology. Although the proposed integrated network management methodology is quite simple, the definition of this methodology is essential for the integrated network management. Using the $Prot\acute{e}g\acute{e}$ to Ontology development, the terms for the integrated network management were defined, along with the OWL and relevant rules, and several methods were implemented according to the proposed methodology. The process in this paper is considered essential for the network expansion and multiple network management.

We propose a new generic design methodology for different types of PSS. Product - Service System (PSS) has received much attention recently from academia and industry because of its benefits. PSS can provide customers values and functionalities, as well as physical products, to fulfill economic, social and environmental goals. Many methodologies have been proposed for designing PSSs. Most of the existing methodologies are domain specific and were proposed to solve specific problems in certain projects. Some methodologies are generic but they provide neither guideline to practitioners and designers nor reflect the differences in various PSS types. As a generic approach to guide practitioners and designers in designing PSS effectively, the proposed methodology also takes into account user involvement, business model and organizational structure. The proposed methodology is demonstrated through design examples of different types of PSSs.

The purpose of this study was to optimize the rice protein extracted using a response surface methodology. The experiment was designed based on a CCD (Central Composite Design), and the independent variables were the high pressure (X₁, 0-400 MPa) and processing time (X₂, 0-10 minutes). The results of the extraction content (Y₁), residue content (Y₂), and recovery yield (Y₃) were fitted to a response surface methodology model (R²= 0.92, 0.92, and 0.93, respectively). Increasing the pressure and processing time has a positive effect on the extraction content (Y₁), residue content (Y₂), and recovery yield (Y₃). Therefore, these high-pressure conditions (independent variables) can significantly affect the improvement in rice protein extraction efficiency. Thus, the optimal conditions of X₁ and X₂ were 400 MPa and 10 min., respectively. Under these optimal conditions, the predicted values of Y₁, Y₂, and Y₃ were 62.93, 57.53 mg/g, and 91.76%, respectively.

The purpose of this study was to optimize the mandarin dry chip manufacturing using a response surface methodology. The experiment was designed based on a CCD (Central Composite Design), and the independent variables were the drying temperature ($X_1$, $50-90^{\circ}C$), drying time ($X_2$, 12-36 hours), and microwave pretreat time ($X_3$, 0-4 minutes). The results of appearance ($Y_5$), color ($Y_6$), taste ($Y_8$) and overall acceptance ($Y_{10}$) were fitted to the response surface methodology model ($R^2=0.86$, 0.88, 0.89, and 0.84, respectively). Increasing the drying temperature and microwave treatment time were negatively evaluated for consumer acceptance. On the other hand, a high value of consumer acceptance was evaluated when the drying time was more than 24 hr. Therefore, the optimal conditions of $X_1$, $X_2$, and $X_3$ were $52.989^{\circ}C$, 24 hr, and 1 min, respectively. Under these optimal conditions, the predicted values of $Y_5$, $Y_6$, $Y_8$, and $Y_{10}$ were 5.066, 5.338, 5.063, and 5.339, respectively.

For reliability and confidentiality of information security systems, the security engineering methodologies are accepted in many organizations. To improve the effectiveness of security engineering, this paper suggests a security methodology ISEM, which considers both product assurance and production processes, takes advantages in terms of quality and cost. To verify the effectiveness of ISEM, this paper introduces the concepts of quality loss, and compares the development costs and quality losses between ISEM and CC through the development of VPN system.
